Tin Bar
What is the meaning of tin bar?
Tin bar is a tin based metal alloy, generally combined with lead, silver, copper, antimony etc to form different tin bar alloy, functioning as solder, people also call it solder bar, or tin solder bar. Tin bar is just made of metal, without any flux as core nor coated with flux, this is one of the difference it has when comparing to cored solder wire.
Production flow of tin bar:
1. Smelting factory of tin bar will weigh the tin ingots and other metals (lead, silver, copper etc) at the correct portion depending on what composition they want to make.
2. They put these ingots at right portion into a smelter and melt them, and during this they will keep stiring the molten tin and other metals which are molten into liquid status, in order to make them well & evenly mixed with each other. This is very important procedure to make a reliable quality of tin bar.
3. Pour the molten liquid tin alloys into dies and cast them into bars, during this procedure there's a cooling system under the dies to help the tin to solidify more quickly.
4. Remove the tin bar out of the dies and pack them into cartons. All done.
What is tin bar used for?
1. Dip soldering. The tin bar solder were molten in a solder bath, and PCB with electronic components are dip into the bath to get the whole PCB assembly at one time. Also this way of technology is used to do tinning of copper wires etc. Comparatively fast soldering speed, though it's manual operation, but faster and more efficient than hand soldering by using tin solder wires.
2. Wave soldering. It's a bit similar function like dip soldering, in order to enhance soldering productivity. But this one is done through automatic wave soldering machine, tin bar solders are molten inside the bath and being blow to create a wave (looks like boiling water), and the PCB and components are put on the tray and being move to connect with the wave to get the PCB soldered.
3. Tin bar is used for soldering metals of copper roofing, car body wiping etc...
